Why do I get the error "[SC] StartService FAILED 1069:" while starting MATLAB Web App Server?

I have been running the development version of MATLAB Web App Server for a while without issue. However, recently when I try to start the server I receive the following error:

Service error

The service command did not execute successfully with
the following error: [SC] StartService FAILED 1069:

The service did not start due to a logon failure.

The 1069 error is due to an incorrect password for the server and worker services.

If you are using the default accounts (e.g., MwWebAppServerR2023b), the password is randomly generated during registration. This error can occur if your company has a password expiration policy set for local accounts.

To reset this password for the services:

1. Open the development Web App Server management app.
2. In the "Service Registration" tab, click "Unregister."
3. If you are using existing local accounts: 
   1. Reset the passwords to the local accounts you are using for the webapps services.
   2. Update the password in the Web App Server management app.
4. Click "Register" to register the accounts again.
5. Try starting the Web App Server again.
